Language is acquired in a natural way, it is like absorbing something naturally, and this is presented too much when learning a second language, so acquiring a second language can be something that does not always need to follow a process, as it would be in this case a method, it is more than all as the example that we set of children by directly relating to two languages , your brain functions like a sponge, absorbs information naturally and processes it until you achieve what you want. This can also happen in adults, they do not always need a method to acquire a second language, they can be given naturally, with an effort that does not need to follow rules to learn what is desired.

When we mean to learn, there is the question changes. At this point if we need to be totally focused on what we want to learn, develop knowledge based or lined by certain criteria or rules that are very necessary to develop excellent learning. When a child or adult focuses and appropriates a method for researching and learning something, in this case a second language, their approach and method has been like a monitor, guiding them for good results. In Krashen's research, it could be seen that, by leaving a natural focus on Learning English, problems were generated, students did not take their responsibilities seriously, for this reason it is best to have guided, explicit, and grounded learning. For this reason, different methods of learning were created when teaching or learning a second language, to have a good development with what you want to learn, so that, at the end of any activity, you can be sure that what was wanted can be achieved.

In conclusion, it is important to be clear about the approach we give to classes or what approach we take ourselves when teaching or learning something. In addition, we must keep in mind that the best thing we can do is always guide ourselves by a method that lets us notice that we are doing things right and we will get the desired results. Only in this way can we rest easy on the learning or teaching processes that we have in charge.
